YORK, NEBRASKA; SAID RIOKERD PATENT OFFICE.

,AND DANIEL HENRY RICKERD, OF

ASSIGNOR, BY MESNE ASSIGNMENTS,

SPECIFICATION forming part of Letters Patent No. 405,581, dated June 18,1889.

Application filed March 14, 1889.

To all whom it may concern.-

Be it known that we, BENJAMIN FRANKLIN MARSHALL, J12, and DANIEL HENRYRICKERD, citizens of the United States, residing at York,

in the county of York and State of Nebraska, have invented a new anduseful Improvement in Door-Locks, of which the following is aspecification.

The invention relates to door-locks of the class known as portable ortravelers locks, adapted to be temporarily attached to a door during theoccupancy of the room.

It consists in a certain novel construction and combination of devicesfully described hereinafter in connection with the drawings, andspecifically pointed out in the claims.

In the drawings, Figure 1 is a perspective View of the improved lockapplied in the operative position to a door. Fig. 2 is a simi- 2o larView of the lock detached from the door.

Fig. 3 is a plan view showing the lock applied to a door having aprojecting casing.

Referring by letter to the drawings, A designates the catch-plate,provided with a longitudinal slot B, and having the spurs O on its innerend to be pressed into the door frame or casing adjacent to the edge ofthe door. To adjust this plate, place it in a horizontal position withthe spurs on its inner end in contact with the surface of the doorcasingand close the door, so that its edge bears against the plate and forcesthe spurs into the casing.

D designates a key-plate, tapered longitudinally and provided on oneside with a series of serrations d cl. The smaller end of the key-plateis inserted in the slot B, the plain or smooth side of the plate bearsagainst the outer side of the face of the door, and the serrations onthe other side of the plate engage the outer end of the slot B andprevent the plate from slipping out of position. The

key-plate is forced through the slot in the catch-plate until it iswedged tightly between the outer end ofthe slot and the door.

If the casing projects beyond the plane of the door, the catch-platemust be set out ac- Serial No. 303,278. (No model.)

cordingly, as shown in Fig. 3 of the drawings, and the swinging buttonor arm E, which is pivoted to the enlarged end of the key-plate, isswung rearwardly, so that its free endbears against the surface of thedoor and holds the end of the key-plate out of contact therewith. Thisswinging button or arm also forms a convenient handle with which tooperate the keyplate.

From the above description it will be seen that the improved lock issimple in construction. It is small, and may be readily carried in thepocket. It may be easily and quickly attached to the door, and it willeffectually prevent the opening of the door from the outside.

The catch-plate A and key-plate D are each provided with a perforationat one corner, so as to enable them to be carried on a key-ring in thepocket of the owner.

Having thus described the invention, we claim 1. In a door-lock, thecombination of the slotted catch-plate affixed to the casing, and thewedge-shaped or tapered key-plate fitting in the slot of the catch-plateand provided with a swinging button or arm to bear at its free endagainst the surface of the door, substantially as Specified.

2. In a door-lock, the combination, with the catch-plate A, bent to formthe tooth C and longitudinally slotted, as at B, of the taperedkey-plate D, adapted to enter the slot B of the plate A, havingserrations cl formed upon its outer edge for engagement with the outeredge of the slot B, and provided with the pivoted wedging-button E, asand for the purpose specified.

In testimony that we claim the foregoing as our own we have heretoaflixed our signatures in presence of two witnesses.
